WEFT-REPLENISHING MECHANISM FOR LOOMS.

Application filed June 17,

To all whom it may concern:

Be it known that we, JOHN VVHITTAKER, a subject of the King of the United Kingdom of Great Britain and Ireland, and resident of Brookside, Wilpshire, in the county of Lancaster, England, and Riel-min) BRADSHAW and Josnrn BRIGGS, subjects oi the King of the United Kingdom of Great Britain and Ireland, and residents of Britannia Mill, Rishton, near Blackburn, in the county of Lancaster, England, have invented new and useful Improvements in Weft-Replenishing Mechanism for Looms, of which the following is a specification.

This invention relates to weft-replenishing mechanism for looms and has for its object an improved form of the jaws at the mouth of a cop magazine in which the cops are held by their heel ends only.

An important advantage of the jaws which form the subject of the present invention is that they admit of the accurate transfer of both cops on skewers and wooden pirns.

In the accompanying drawings, Figures 1 and 2 are horizontal sections through the extreme bottom of the magazine, Figure 1 showing the position of the aws during the passage of a skewer and Figure 2 showing the same during the passage of a wooden pirn. Figure 3 is an elevation of the pivoted jaws, and Figure 4 is an elevation of the same in an alternative form.

Apart from the form of the jaws, the magazine is of already known construction.

Referring to the drawings, 1 is the heel end of a skewer and 2 the heel end of a wooden pirn. The fixed jaws 3, 4, of the magazine, bear on the cylindrical portion of the heel of the skewer or pirn, the jaw 4 being extended so as to bear against the lefthand end of the heel (as viewed in the drawings).

There are three pivoted jaws; 5, 6 and 7 which may conveniently be mounted, as heretofore proposed, on a single pivot, 8, fixed 1920. Serial No. 389,747.

to the magazine 11 and caused to press against the heel of the skewer or pirn by springs 9 and 10 which are shown broken oii in Figures 3 and 4:.

In the form of the invention shown in Figures 1, 2 and 3, the jaws 5 and 6 are connected together to form a single piece, while jaw 7 is free to move independently of the jaws 5 and 6. Jaw 7 bears on the righthand end oii the cylindrical portion of the heel of the skewer or pirn, jaw 6 bears against the end of the heel, and jaw 5 bears against the left-hand end of the heel and also on the skewer or pirn itself to the left of the heel.

By comparing Figures 1 and 2 it will be seen that the jaw 5 is further towards the "front in Figure 2 than. in Figure 1 on account or" the greater diameter of the pirn, as compared with that of the skewer. The jaw 6 therefore is also further forward, but its function of retaining the heel from movement to the right is not thereby affected. The jaw 7, however, is in the same position in the two cases.

In an alternative form of the invention shown in Figures 1, 2 and 4, the jaws 6 and 7 are connected together, while the jaw 5 is independent. For convenience in construction, the jaws 5 and 6 in the form first descrbed and the jaws 6 and 7 in the form last described are shown connected together but such connect-ion is not essential to the device.

Having described our invention, we declare that what we claim and desire to secure by Letters Patent is 1. In weft-replenishing mechanism for looms, a cop magazine of the type described, having three pivoted jaws of which the first bears on the end of the heel of the skewer or pirn, the second bears on the cylindrical portion of the heel close to that same end of the heel while the third jaw bears upon the skewer or pirn beyond the heel, one of the two last-named jaws being movable independently of the other two.

2. In Weft-replenishing mechanism for heel close to the first jaw, substantially as looms, a. cop magazine of the type described, described. 10 having three pivoted jaws, of which the first In Witness whereof, We have hereunto subbears on the end of the heel of the skewer scribed our names.

5 or pirn, the second bears on the skewer or pirn beyond the heel, while the third can JOHN WHITTAKER. move independently of the first two and RICHARD BRADSHAW. bears upon the cylindrical portion of the JOSEPH BRIGGS.
